  • Introducing Fuzzy Cognitive Maps for decision making in precision agriculture 

    Markinos, Ath; Papageorgiou, El; Stylios, Chr; Gemtos, Th (2007)
    A Fuzzy Cognitive Maps (FCMs) is a modelling methodology based on exploiting knowledge and experience. It comprises the main advantages of fuzzy logic and neural networks, representing a graphical model that consists of ...
  • Introducing intelligence in electronic healthcare systems: State of the art and future trends 

    Maglogiannis, I. (2009)
    This chapter introduces intelligent technologies applied in electronic healthcare systems and services. It presents an overview of healthcare technologies that enable the advanced patient data acquisition and management ...
  • A multilateral design process of decision support systems: Some issues 

    Sagheb-Tehrani, M.; Manussaridis, Z.; Maysami, R. C. (2005)
    A discussion is presented of why some Decision Support Systems (DDS) that some firms have developed cannot satisfy the users' needs. Trying to develop a specific Decision Support System (DSS) for Vehicle Routing and ...
  • People, robots and systemic decision making 

    Blackmore, B. S.; Blackmore, C. P. (2007)
    People can make decisions intuitively, based on their values and perceptions which take account of their contexts, so demonstrating a systemic approach. Other decisions processes are more rational than intuitive and can ...
  • Precision agriculture applications in horticultural crops in greece and worldwide 

    Gemtos, T. A.; Fountas, S.; Aggelopoulou, K. (2011)
    Precision agriculture is the management of spatial and temporal variability of the fields using ICT. The application in horticultural crops was developed in the last ten years. Data are collected from different sources ...
  • Projection based clustering of gene expression data 

    Tasoulis, S. K.; Plagianakos, V. P.; Tasoulis, D. K. (2010)
    The microarray DNA technologies have given researchers the ability to examine, discover and monitor thousands of genes in a single experiment. Nonetheless, the tremendous amount of data that can be obtained from microarray ...
  • Revisiting evolutionary information filtering 

    Nanas, N.; Kodovas, S.; Vavalis, M. (2010)
    Adaptive Information Filtering seeks a solution to the problem of information overload through a tailored representation of the user's interests, called user profile, which constantly adapts to changes in them. Evolutionary ...
  • RuleMR: Classification rule discovery with MapReduce 

    Kolias, V.; Kolias, C.; Anagnostopoulos, I.; Kayafas, E. (2014)
    The vast amounts of data generated, exchanged and consumed on a daily basis by contemporary networks and devices renders their analysis a cumbersome procedure with inherent difficulties. On the one hand, the need for ...
  • Skin lesions characterisation utilising clustering algorithms 

    Tasoulis, S. K.; Doukas, C. N.; Maglogiannis, I.; Plagianakos, V. P. (2010)
    In this paper we propose a clustering technique for the recognition of pigmented skin lesions in dermatological images. It is known that computer vision-based diagnosis systems have been used aiming mostly at the early ...
  • A study of cAnt-Miner2 parameters using medical data sets 

    Michelakos, I.; Papageorgiou, E. I.; Vasilakopoulos, M. (2010)
    This paper presents a study of the user-defined parameters of the cAnt-Miner2 algorithm which extended the approach of coping with continuous attributes that was introduced by the cAnt-Miner algorithm. Experiments on two ...
  • A systems view of agricultural robots 

    Blackmore, B. S. (2007)
    Many agricultural robots are being built around the world but, in most cases, these projects are focussing on developing the technologies for individual machines. This paper attempts to broaden the scope by taking a systems ...
  • Towards the 8-dot Nemeth Braille code 

    Martos, A.; Kouroupetroglou, G.; Argyropoulos, V.; Deligiorgi, D. (2014)
    In this work, a language-independent design methodology for the systematic development of an 8-dot braille code, has been applied to the Nemeth code. First, we set the design principles: compression, intra-similarity, ...
  • Tracking differential evolution algorithms: An adaptive approach through multinomial distribution tracking with exponential forgetting 

    Epitropakis, M. G.; Tasoulis, D. K.; Pavlidis, N. G.; Plagianakos, V. P.; Vrahatis, M. N. (2012)
    Several Differential Evolution variants with modified search dynamics have been recently proposed, to improve the performance of the method. This work borrows ideas from adaptive filter theory to develop an "online" ...
  • Unsupervised detection of fibrosis in microscopy images using fractals and fuzzy c-means clustering 

    Tasoulis, S. K.; Maglogiannis, I.; Plagianakos, V. P. (2012)
    The advances in improved fluorescent probes and better cameras in collaboration with the advent of computers in imaging and image analysis, assist the task of diagnosis in many fields of biologic and medical research. In ...
  • Using multicast transfers in the replica migration problem: Formulation and scheduling heuristics 

    Tziritas, N.; Loukopoulos, T.; Lampsas, P.; Lalis, S. (2009)
    Performing replica migrations in the minimum possible time, also called the Replica Migration Problem (RMP), is crucial in distributed systems using replication. In this paper we tackle RMP when multicast transfers are ...
